Why Class A Serialized
Each Class A burette in this range is individually serialized and carries a tighter volumetric tolerance than a Class B burette, which is why it is specified for certified accuracy work and tender compliance where a traceable calibration record is required. For routine teaching use where this level of certification isn't required, see Burette Class-B with PTFE Key Stopcock.
Frequently Asked Questions
What does "Class A serialized" mean?
It means the burette meets the tighter Class A volumetric tolerance and carries its own individual serial number, so its calibration can be traced and verified individually.
Is a Class B version available?
Yes, see Burette Class-B with PTFE Key Stopcock for the standard-tolerance option.
